We have attempted, therefore, in this analysis of money-making to apply this test, because the practice or habit or influence that pays is that which is in accord so far with the principles underlying this branch of social science. We have seen, according to this standard, that it is the duty of all to adopt money-making as a conscious aim; that the money is to be economically used, the final object being net profit, that balance or remainder which is carried forward as created capital. Inability to increase a fixed income does not absolve one from the duty of doing one's part in the creation of capital through thrift and saving. The business enterprise, moreover, is required by economic necessity to aim at money-making--meaning, however, profits in the long run rather than immediate or temporary gains. Such permanent returns can only be sought through adherence to ethical principles and although this aim at profits becomes the power plant which drives the business machine, the latter gives its energies and attention more directly to the rendering of service. Concentration upon service tends to make a man relatively efficient therein, but argues a relative unfamiliarity with the field of others, from which we infer the advisability of confining one's activity to the thing he has learned to do best. As an example of this, he should avoid placing his surplus capital or savings in outside enterprises where they will partake of risks that are unknown to him, nor should he attempt to employ his savings at all with the purpose of making money, unless, indeed, he can use them as capital in his own business. The focusing of attention on one's own function also implies and explains the custom of placing upon participants in a business transaction the responsibility each for his own side, a custom which is economically justified but which must be kept within proper limits, as is fully recognized by the business men who are successful and who therefore become models or examples for the guidance of other men, influencing the latter towards high ideals.
